質問 # 48
You have an Azure SQL database.
Users report that the executions of a stored procedure are slower than usual. You suspect that a regressed
query is causing the performance issue.
You need to view the query execution plan to verify whether a regressed query is causing the issue. The
solution must minimize effort.
What should you use?

A. Performance Recommendations in the Azure portal
B. Query Performance Insight in the Azure portal
C. Query Store in Microsoft SQL Server Management Studio (SSMS)
D. Extended Events in Microsoft SQL Server Management Studio (SSMS)

正解：C

解説：
Section: [none]
Explanation:
Use the Query Store Page in SQL Server Management Studio.
Query performance regressions caused by execution plan changes can be non-trivial and time consuming to
resolve.
Since the Query Store retains multiple execution plans per query, it can enforce policies to direct the Query
Processor to use a specific execution plan for a query. This is referred to as plan forcing. Plan forcing in Query
Store is provided by using a mechanism similar to the USE PLAN query hint, but it does not require any change
in user applications. Plan forcing can resolve a query performance regression caused by a plan change in a
very short period of time.

query-store

質問 # 49
You are building an Azure virtual machine.
You allocate two 1-TiB, P30 premium storage disks to the virtual machine. Each disk provides 5,000 IOPS.
You plan to migrate an on-premises instance of Microsoft SQL Server to the virtual machine. The instance has a database that contains a 1.2-TiB data file. The database requires 10,000 IOPS.
You need to configure storage for the virtual machine to support the database.
Which three objects should you create in sequence? To answer, move the appropriate objects from the list of objects to the answer area and arrange them in the correct order.

正解：

解説：

Explanation:

Follow these same steps to create striped virtual disk:
* Create Log Storage Pool.
* Create Virtual Disk
* Create Volume
Box 1: a storage pool
Box 2: a virtual disk that uses stripe layout
Disk Striping: Use multiple disks and stripe them together to get a combined higher IOPS and Throughput limit. The combined limit per VM should be higher than the combined limits of attached premium disks.
Box 3: a volume

質問 # 50
You are building a database in an Azure Synapse Analytics serverless SQL pool.
You have data stored in Parquet files in an Azure Data Lake Storage Gen2 container.
Records are structured as shown in the following sample.

The records contain two applicants at most.
You need to build a table that includes only the address fields.
How should you complete the Transact-SQL statement? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

正解：

解説：

Explanation:

Box 1: CREATE EXTERNAL TABLE
An external table points to data located in Hadoop, Azure Storage blob, or Azure Data Lake Storage. External tables are used to read data from files or write data to files in Azure Storage. With Synapse SQL, you can use external tables to read external data using dedicated SQL pool or serverless SQL pool.
Syntax:
CREATE EXTERNAL TABLE { database_name.schema_name.table_name | schema_name.table_name | table_name } ( <column_definition> [ ,...n ] ) WITH ( LOCATION = 'folder_or_filepath', DATA_SOURCE = external_data_source_name, FILE_FORMAT = external_file_format_name Box 2. OPENROWSET When using serverless SQL pool, CETAS is used to create an external table and export query results to Azure Storage Blob or Azure Data Lake Storage Gen2.
Example:
AS
SELECT decennialTime, stateName, SUM(population) AS population
FROM
OPENROWSET(BULK 'https://azureopendatastorage.blob.core.windows.net/censusdatacontainer/release
/us_population_county/year=*/*.parquet',
FORMAT='PARQUET') AS [r]
GROUP BY decennialTime, stateName
GO
